A green laser will happily burn out sensors, but you'd have to really work at it to burn up all of the sensor because the laser light will typically only fry a couple of pixels at the time.

It's not a magical 'point and fry' solution, more like a take up position and stand around for half an hour or so while the laser systematically hits every bit of the sensor long enough to fry it. A hammer would be a lot more effective (assuming you can reach the camera).

So would a can of spray paint.

What it can do quite easily is mess with the AGC / white balance while a big part of the image is obscured by a bright green blog. As a temporary effect this may be good enough, and has the advantage of not being property damage.

For confirmation: [1] is a video of someone assaulting their webcam with a 1.5w blue laser. All it does is create a few horizontal lines, burn a few tiny marks on the image, and discolor the highlights.
